微机测控系统在行走式节水灌溉试验台车上的应用

The Application of Microcomputer Control System on the Walking-Type Irrigation Test Trolley

介绍了行走式节水灌溉试验台车微机测控系统硬件的设计,包括传感器和放大器、数据采集卡、电磁阀、电机控制电路等,还介绍了测控系统软件的设计,采用VisualBasic程序控制多功能数据采集卡来获取外界的数据、控制电磁阀的开和关、电机的起停及正反转。试验结果表明,测控系统设计合理,达到测控要求,能满足行走式节水灌溉技术的试验要求。

In the paper the hardware system design of microcomputer control system on the walking-type irrigation test trolley was introduced.It included the sensors,amplifier,data acquisition card,electromagnetic valve and motor control circuit.And the software system design was introduced,too.The results showed that the design of control system was reasonable and could meet the need of control and test requirement.
